IBD fuses are designed for the protection of HV/LV distribution transformers. The fuse technology is known

as “enclosed” melting. It ensures against any visible evidence of the fuse during its operation.

The main features include:

• enameled ceramic housing

• nickle-plated brass end caps

• solid silver fuse elements

• waterproof system for outdoor use.

IBD fuses satisfy existing operational constraints for electric networks.

Their characteristics are based on operation at ambient temperatures ranging from -25°c to +40°c, and a

maximum altitude of 1000 meters.

The selection of fuses for the protection of HV/LV

transformers must take into account:

a) transient currents occuring in the installation

when the transformer power is switched on

b) overload currents related to normal operation

of the transformer and liable to cause prematu-

re agin.

As a rule of thumb:

Fuse rating ∆1.7 x transformer rated current

This relationship is given for an ambient tempe-

rature not exceeding 40°c. Beyond this, a dera-

ting factor A1 must be used

with q = ambient temperature in °c.

E.g., a 40A rated fuse installed under 60°c

ambient must be treated as a 34A rated fuse.

The table, opposite, may also be used. It has been

computed using peak transient currents from 8 to

15 times the transformer current rating and a 130

% overload rate.

Using this table also means applying the tempe-

rature derating factor A1 to the selected rating

when ambient exceeds 40°c in the fuse

environment.

A1 = V120-θ

The indicating device enables electrical actuating of the opening mechanism for a circuit or triggering of

an indicator during the melting of a fuse equipped with a trip-indicator. This very robust and original

device means freedom for any mechanical system and offers the advantage of being able to incorporate

a microswitch unit or units according to the equipment configuration.

Presentation

FR-type fuses are designed to protect HV/LV power distribution transformers. Designed to be coordinated

with other equipment, these current-limiting fuses interrupt fault currents before they reach their peak. The

fault current is interrupted inside the fuse body and although this is very fast there is no sign of it outside.

The main elements in these fuses are:

• a barrel of class F insulating synthetic material

• nickel plated aluminum end contacts

• very pure silver fuse elements

• composite material fuse element holder to withstand high temperatures

Thanks to their structure, based on a synthetic material, FR fuses are the perfect answer to the stresses

involved in use inside HV bays and fuse chambers.

5.5kV, 8.25kV and 15.5kV - CS 3 Series

5kV, 8 kV and 15kV Ferrule mounted fuses

Amp-trap CS-3 E-rated 5kV, 8kV and 15kV fuses have either 2”

or 3” diameter barrels with ferrules and are mounted in spring

reinforced clips. They are UL listed as “general purpose current-

limiting fuses” and are for use indoors (or outdoors in a weath-

erproof enclosure). The unique time-current characteristic of

Ferraz Shawmut E-rated fuses allows them to be closely sized

to transformer full-load rated current, as recommended by IEEE

guidelines, without being affected by normal magnetizing

inrush current. CS-3 fuses are typically sized at transformer

rated current of 133%, thereby providing superior overall pro-

tection.

Features /Benefits

• UL Listed for compatibility with UL listed equipment

• Ferrule mounting for standard clips and

interchangeability with other brands of fuses

• Current Limiting for superior equipment protection

• Blown-fuse indicator gives positive identification

of open fuse

• Non-venting for silent operation

Definitions

E-rating

E-rated fuses operate as follows:

100E or less - must melt in 300 seconds (5 mins.)

on 200 to 240% of E (ampere) rating.

Over 100E - must melt in 600 seconds (10 mins.)

on 220 to 264% of E (ampere) rating.

Example - A 100E fuse must melt in 300 seconds

with an applied current of 200 to 240 amperes.

General Purpose Current-Limiting Fuse

A general purpose current-limiting power fuse is

one that is capable of interrupting all currents

from its rated interrupting rating down to the

current that causes melting of the fusible ele-

ment in one hour.

Spring-Reinforced Clips for CS-3 Fuses:

228-700-530 (One pair of clips)

For 3” diameter, 2 barrels max.

Amp-trap Bolt-in Series E-rated fuses are single, double or triple

barrel (3” diam.) with end mounts designed for bolting directly

to equipment bus or terminal pads. They are UL listed and are

for use indoors (or outdoors in a weatherproof enclosure). The

unique time-current characteristic of Ferraz Shawmut E-rated

fuses allows them to be closely sized to transformer full load

rated current, as recommended by IEEE guidelines, without

being affected by normal magnetizing inrush current.

Bolt-in fuses are typically sized at transformer rated current of

133%, thereby providing superior overall protection.

Features /Benefits

• UL Listed for compatibility with UL listed

equipment

• Bolt-in mounting for direct connection to bus

or terminals

• Current Limiting for superior equipment

protection

• Blown-fuse indicator gives positive identification

of open fuse

• Non-venting for silent operation

E-rating

E-rated fuses operate as follows:

Over 100E - must melt in 600 seconds (10 mins.)

on 220 to 264% of E (ampere) rating.

Example - A 750E fuse must melt in 600 seconds

with an applied current of 1650 to 1980 amperes.

General Purpose Current-Limiting Fuse

A general purpose current-limiting power fuse is

one that is capable of interrupting all currents from

its rated interrupting rating down to the current

that causes melting of the fusible

element in one hour.

R-RATED MOTOR STARTER FUSES

Amp-trap®R-rated fuses are current-limiting, high inter-

rupting rating fuses intended for the short-circuit protec-

tion of medium voltage motors and motor controllers. R-

rated fuses have a minimum interrupting rating and must

be coordinated with overload relays in combination

motor starters. The motor starter manufacturer generally

specifies the R-rated fuse size. Amp-trap R-rated fuses

are-rated 2R to 36R, at 2.4, 4.8, and 7.2kV. 4.8 and 7.2kV

fuses are UL Recognized. The 4.8kV (A480R) is available

with hookeye tab. The 7.2kV (A072F) series has the same

dimensions as the 4.8kV (A480R), allowing smaller 7.2kV

equipment or 4.8kV upgrades. The A072B is a bolt-in

7.2kV fuse.

Features /Benefits

• Ferrule mounting for standard clips and

interchangeability with other brands of fuses.

• 7.2kV series has the same dimensions as

4.8kV fuses, allowing compact, higher

voltage-rated equipment designs.

• 7,2kV bolt-in design for improved

design flexibility.

• Optional hookeye on 4.8 kV for non

load-break isolation by hookstick.

Presentation

The insulation fault indicator is presented in the form of a compact case made of a highly sturdy synthetic

material. A window on the front enables the viewing of a red warning light in case of operation. This

signal may be seen from 10 meters away, across a 120 ° sector.

The IDT20 Comp counts current pulses due to lightning - A6- digits electromechanical meter indicate the

number of lightning strikes.

Two conductive contacts on the front allow the indicator to be reset.

The case contains a 16 mm diameter hole for the passage of a ground cable. The indicator is delivered

with an 80 cm cable section and two crimping sleeves to prevent the ground circuit from being cut during

installation. Two openings on the back enable the device to be attached to the pole by metal strip.

Operation

Ground currents caused by insulation faults are measured by an integrated current transformer. An electro-

nic panel processes the transformer output signal and controls the operation of the warning light in the

event it exceeds a preset threshold. The signal is maintained even after power on the line has been dis-

connected, enabling the operator to quickly detect the fault location.

Resetting and testing of the indicator are ensured by an IDT 101 type reset device.

A/ Fixing indicator to electric pole

• The indicator is installed in a horizontal position, facing in either direction.

• The indicator may be attached to a wooden or concrete pole.

• On concrete poles, the indicator may be placed either on flat side or in a corner.

The different configurations are described below.

• Two openings located at the back of the case are designed to accommodate a stainless steel strip, 20

mm wide and 0.4 mm thick, in order to fix the indicator to the post by hooping.

• The hole in the indicator case must be positioned as closely as possible to the ground cable.

WARNING: During attachment, the strip must pass between the ground cable and the post in order to

prevent the cable from being tightened against the post during hooping.

Functional description

Ground faults in general

In networks with directly earthed zero-point, a

ground fault is equivalent to a phase-to-ground

short circuit. In that case the current magnitude will

be somewhat less than in the case of a phase-to-

phase short circuit. For networks that do not have

directly earthed zero-point, the magnitude of the

singular ground fault current is ruled by the size of

the galvanically interconnected network, voltage

level, type of cable and the zero-point equipment.

Ground Fault Element

The Ground Fault Element is a summing current

transformer (CT) which generates a current when

the vectorial sum of the 3 phase currents becomes

different from zero, i.e. during ground fault. With

no ground fault, the vectorial sum is approximately zero.

Mounting

Ground faults in Element

The element connects to the indicator

via its ready-mounted cable (2.0 m).

Multi-core cable: The element is

mounted on the screened part of the

cable, below the stripback point,

according to the mounting instruc-

tions. The screen is turned back under-

neath the flexible CT-core and termina-

ted at the ground point. The principle

is shown in figure opposite.

Ground faults Indicator

The Indicator should be mounted in a readily visible

location. It can be mounted on a pole or a wall with

the two enclosed self-threading screws. The Indicator

is also suited for mounting with stainless steel or PVC

cable ties. Both options are illustrated in figure above.

Remove the front cover of the indicator to access

holes for screws/ties. See figure for further details.

Mounting of

Ground Fault Indicator

Overview

Cabletroll 2500 is a ground fault sensing system. It

consists of a Ground Fault Element and Ground

Fault Indicator. It can be mounted in high voltage

underground cable distribution networks with sys-

tem voltage from 6 to 36 kV.

The sealed Ground Fault Element mounts on most

widely used cable types, while the weatherproof

indicator is well suited for outdoor mounting (See

fig. 1).

The indicator is fitted with a high intensity LED for

local indication and an optional Xenon flash unit. It

is also equipped with a pair of relay contacts for

connection to remote indicators, which communi-

cate via cable and/or radio.

The trip level for ground fault can be set on-site to

fixed values of 40A, 80A or 120A. It is factory set to

40A. In addition, the trip level can be continuously

adjusted in the ranges 5-40A, 8-80A or 12-120A.

System description

Cabletroll 2700 is a complete system for indication of earth-fault and short circuit faults in an underground

6-36V cable network.

The system consist of three different modules:

• Ground fault element with a split core for sensing the imbalance during ground faults

• 2 (or3) sensors for detecting short-circuits

• Processing unit including power supply and indication unit with flashing LED's for local indication

and relay contacts for remote signalling, controlled by a microcontroller.

Trip level for ground fault is continuously adjustable within the range of 5-240A. Short circuit trip level is

adjustable within the range of 300-1000A.

The system has separate indicators for ground fault and short-circuit faults.

Three LED's show which phases are involved in the short circuit.

For remote signaling, two pairs of relay contacts are available; ground fault and short circuit.

Operating mode

Functions are controlled by a microprocessor and all time delays and operation of the indication unit are

programmed in software, making it very easy to adapt to different requirements.

Different operating modes are available:

• Immediate indication of both permanent and transient faults

• Immediate local and remote indication of both permanent and transient faults causing circuit

breaker tripping

• Postponed operation of relay contacts, allowing closing-cycles to finish before

remote-indication is activated Indication of permanent faults only

• Both timer and voltage reset can be enabled or disabled independently

Directional fault current indicator

for underground systems

Presentation

CABLETROLL 3600 directional Fault Current Indicators (FCI) are designed to help the operator locate faults

on underground lines. They detect both single phase-to-ground (PTG) and phase-to-phase (PTP) faults in

systems with 300A impedance or compensated neutral grounding. And they use a brand-new detection

technique that offers significant advantages over the conventional technique of existing detectors working

on current thresholds. That new technology means that unlike conventional detectors, they can operate

on systems with high capacitive current (combined overhead/underground networks with a high propor-

tion of cable, very long underground networks).

The CABLETROLL 3600 FCI is capable of discriminating between PTP and PTG faults, and indicating the

direction of the latter type.

It can be used on networks from 6 to 36 kV for the following applications:

CABLETROLL 3600 LDAC:

installed on strategic points in the network (switching points, branching points), it assists the

operator by visually signaling the passage of a PTG or PTP fault current.

CABLETROLL 3600 LDAC LV:

when used in combination with remote-controlled switchgear, it assists the operator in remote

control by providing contacts that alert the remote control system to the passage of a PTG or PTP

fault current.

CABLETROLL 3600 LDAU:

installed temporarily on a disturbed network, it identifies what sections are responsible for faults

and gives a time and date system the data required to analyze faults, whether persistent or

transient.

Cabletroll 3600

The CABLETROLL 3600 works on the principle of directional fault indication described in EDF

patent 9209549.

The following block diagram shows the CABLETROLL 3600 indicator's main circuits.

In the initial milliseconds after a PTG fault, voltage and current transients are generated on the system.

Using a microprocessor to interpret the phase displacement between residual voltage and residual current,

the circuit can indicate in which direction the PTG fault is located (up-line or down-line of the indicator's

pick-up coils).

For PTP faults the working principle is that of an ammeter (current threshold).

There are 6 standard models:

MV Fault Indicator

Cabletroll 3600

General

When a CABLETROLL 3600 detects a fault current, it alerts the operator either visually with a signal light

or through contacts (CABLETROLL 3600 AC LV or AU).

As soon as the existence of a fault is confirmed, the signal light on the CABLETROLL 3600 lights up and

stays lit until one of the following events occurs:

• Forward voltage returns to the HV line (voltage reset).

• The internal 2 hour time delay ends (timer reset).

• The indicator is reset by the operator using either the reset button on the front of the main box or the

COMTROLL infrared remote control unit (manual reset).

PTG fault indication

The principle of directional PTG fault indication is to

locate what part of the line is the origin of a PTG

fault. To do this each pick-up coil has a GREEN sig-

nal and a RED signal. The coils must be mounted

in such a way that the GREEN signal is on the BUS-

BAR side and the RED signal is on the NETWORK

side.

If the GREEN signal light is lit up, the fault is on the

GREEN side, i.e. the BUSBAR side.

If the RED signal light is lit up, the fault is on the RED

side, i.e. the NETWORK side.

PTP fault indication

In this case the CABLETROLL 3600 FCI works like a conven-

tional fault indicator and no direction is indicated. All the fault

indicators between the feeding substation and the fault flash

the green signal light and the red signal light alternately

(once every second).

PTG faults

Any PTG fault characterized by a residual current

over 60A peak + 10A and a residual voltage of 9kV

+ 2kV is detected.

Once those thresholds are exceeded, the fault indi-

cator waits 40 ms to detect a residual voltage Vr

greater than 3.5kV ± 0.5kV before indicating that

there is indeed a fault.

Double PTG faults

A fault considered as a "double PTG fault" consists

of a simultaneous PTG fault on two different phases

in a system powered by the same HV transformer

but grounded at two geographically distant points.

The two faults may be located on the same feeder

or on two different feeders. In this case any fault

characterized by a residual current over 250Arms ±

50A is detected.

PTP faults

Any PTP fault characterized by a current over

450Arms + 80A is detected.

Return of forward voltage

The return of forward HV voltage (resetting the FCI)

is accepted when voltage on the system is at least

10kVrms + 2kV.

The CABLETROLL 3600 FCI consists of six parts:

• Voltage measurement:

subassembly consisting of a male WAGO-type ter-

mination ref. 723-604/000-042 (see connection

diagram) connected to a 7 m (or optional 12 m)

cable. This cable is then connected to the termi-

nal block on the main unit of the FCI. The male

connector is connected to a female part (not sup-

plied with the FCI) that leads to the portable ter-

minations for disconnectable connectors (not sup-

plied with the indicator).

• Current measurement:

subassembly consisting of three current sensors,

each with a detection element with its own cable

and a collar to fasten the sensor on the HV

cables. The three cables running out from the

sensors are fitted with a current transformer (CT)

connector (see connection diagram) that must be

connected to the current sensor cable

(see hereafter).

• Current sensor cable:

7 m (or optional 12 m) cable connected to a con-

nector. One end of this cable must be connected

via CT connectors to the current sensors and the

other to the terminal block of the main FCI unit.

• Multi-core cable:

7 m (or optional 12 m) cable to connect the dis-

play unit to the main FCI unit.

• Main unit containing:

the electronic board, the power supply, the TEST

and RESET buttons and the terminal blocks for

connection to outside elements.

• Display unit consisting of a weatherproof and impact resistant casing containing the green and red signal

lights. This unit must be installed outside the substation or the cubicle.

Functional description

Linetroll®111Ks fault sensing is based on detection

of the electromagnetic field below the conductors.

The unit is fully self-contained; no external transfor-

mers or connections of any kind is required.

To determine whether or not the line is faulted, the

indicator looks for a specific sequence in the line

conditions before it starts flashing. The general

sequence is as follows.

1. The line should be energized for at least

3 seconds.

2. The line current should increase rapidly above the

value set by the user (the nominal trip level).

3. The line should be de-energized.However, the

user may program the operating criteria to suit

local requirements by manipulating a bank of

microswitches inside the indicator.

Overview

Linetroll®111K indicators are used to locate short-circuit and earth faults in overhead power distribution

networks. Linetroll 111K is a 3-phase unit fully covering the different types of potential fault configurations.

Indicators are placed at strategic locations along the line, such as after branching points and sectionalisers.

The indicator may be pole-mounted, 3-5 meters below the conductors, by means of screws or wrapping-

bands. Live line mounting is done safely, easily and rapidly.

Upon detection of a line fault, the indicator gives off an intermittant Xenon gas flash. This flash can be seen

at up to 200 - 300 metres distance in full daylight and 2 - 3 km at night. The indicator lens allows for uni-

form 360 degree monitoring. Upon fault sensing, all indicators installed between the feeding substation and

the fault will operate. Indicators place behind the fault remain idle.

Presentation

LINETROLL®3500 is a pole-mounted intelligent Fault Current Indicator (FCI) for use in electrical power net-

works. It uses brand-new detection technology that provides major benefits over previous FCI technology.

LT3500 aims at tracking down the fault site rather than monitoring the exact fault current level.

FCIs contribute to improving the quality of supply in electrical distribution networks by providing instant

information about fault sites. Based on this information, power rerouting and repair work can commence

quickly. Outage duration and the use of manpower for fault-searching can be reduced by as much as 75%,

a substantial saving potential for any utility.

For Distribution Automation (DA) purposes, or in combination with remote-controlled switchgear, FCIs

used as in-formation sources represent a good alternative to automatic reclosers and sectionalisers.

Reconnection of faulted lines as well as disconnection of healthy lines is avoided. Wear and tear of person-

nel and equipment is reduced.

Strategic application (large numbers) of FCIs represents an important tool in the search for optimum elec-

trical energy supply quality and price. For any utility, the use of FCIs translates to increased earnings and

improved goodwill and credibility among customers.

LINETROLL® 3500 is designed for application on 1- or 3-phase overhead distribution lines at voltages from

6-132 kV. It is able to discriminate between phase-to-phase (PTP) faults and phase-to-ground (PTG) faults

and offers direc-tional capabilities on PTG faults, pointing towards the fault site.

LT 3500 represents a breakthrough in FCI performance and is applicable in networks of any neutral earth-

ing method. The basic version of the unit exhibits 1 out of 2 available factory default characteristics, exclu-

sively tailored for service in the following types of network: solid earthing versus impedance earthing or

isolated networks.

It is designed to flawlessly meet the challenges of networks that undergo extensions and/or modifications,

power re-routing and heavy load variations. All of this without the need for time-consuming network

capacitance and fault current magnitude calculations, saving a lot of expensive time. The trick is that, con-

trary to earlier fault indicator generations, LT3500's performance remains uninfluenced by capacitive dis-

charge currents when applied in isolated or impedance earthed networks.

Unmatched application flexibility and product lifetime is achieved through modular hardware design and

software upgradeability.

Several methods of fault detection can be utilised simultaneously, offering many possibilities for adapting

the function of the unit to some of the protection relay characteristics.

Maintenance requirements are very low thanks to sophisticated power management and a selection of

power supply packs of adequate capacity.

APPLICATION OF LINETROLL®3500

When LT3500 detects a fault current, it will indicate

this by flashing lights or by other means (optional).

The unit is able to discriminate between PTG and

PTP faults on any kind of network with regard to the

earthing method in use.

The fault indicator light will keep flashing until a pre-

determined automatic reset condition is fulfilled.

Such an automatic reset condition can be the return

of voltage to the line (voltage reset), time lapsed

since fault occurred (timer reset) or other.

Manual reset can be carried out on-site by rotating

the display unit to the RESET position, either by

hand or by use of a special TEST/RESET TOOL. The

test/reset tool must be used when the indicator can-

not be reached from the ground.

Performance in coil- (Petersen),

coil+ resistor-, resistor earthed

networks and isolated networks.

PTG faults

All LT3500s mounted in the network supplied from

the same feeder will indicate, flashing a single-color

light, red or green. The color determines the relative

direction to the fault site.

When approaching the front of the indicator, i.e.

when you see the indicator in front of the pole:

a) if the indication color is red; turn back along

the line, the fault site is in the opposite direction

b) if the indication color is green; continue for-

ward along the line, the fault site lies ahead

PTP faults

LT3500s mounted along the fault current path be-

tween the feeder and the fault site will indicate,

flashing alternating red and green lights.

Bi-colored alternating indication means that a PTP

fault has occurred downstream from the indicator.

PTG faults and PTP faults are indicated equally.

The criteria for detection and indication of PTG and PTP faults can be programmed individually, compris-

ing a combination of di/dt and overcurrent techniques.

Only LT3500s mounted along a fault current path between a feeder and the fault site will indicate by flash-

ing lights.

Inversely, a fault site should be located downstream from a flashing FCI. More precisely, the fault site should

be located between the last flashing FCI and the first idle FCI.

Linetroll 3500

LT3500 is the result of several years of research, development and testing aimed at setting new standards

for re-liability and functionality of FCIs.

A few hints

The unit continuously monitors the electromagnetic field on site. It looks for particular sequences of field

changes to take place. Upon recognition of such a sequence, the unit samples and stores information in

memory for immediate analysis. Based on analysis, the unit either indicates a faulted line or resumes triv-

ial surveillance. The exact sensitivity to fault current magnitude is not critical for correct operation.

Fault category display

Phase-to-Ground and Phase-to-Phase faults can be indicated individually, as can transient faults versus per-

manent faults. For on-site monitoring, faults are indicated by flashing lamps in the display unit. The flash-

ing pattern defines what kind of fault the unit has detected. The display unit can be rotated horizontally

to allow easy monitoring from any position.

Directionality

A great advantage to LT3500 is its directional capability. In impedance earthed or isolated networks the

unit is able to tell its relative position to a phase-to-ground fault site.

Maintenance

Maintenance of FCIs normally involves replacing the batteries. A range of battery packs is available for

LT3500, allowing some flexibility with respect to service intervals.

Directional fault current indicator for

overhead lines

Présentation

LINETROLL 3600 directional Fault Current Indicators (FCI) are designed to help the operator locate faults on

overhead lines. They detect both single phase-to-ground (PTG) and phase-to-phase (PTP) faults in systems

with 300A impedance or compensated neutral grounding. And they use a brand-new detection technique

that offers significant advantages over the conventional technique of existing detectors working on current

thresholds. That new technology means that unlike conventional detectors, they can operate on systems

with high capacitive current (combined overhead/underground networks with a high proportion of cable).

The LINETROLL 3600 FCI is capable of discriminating between PTP and PTG faults, and indicating the

direction of the latter type.

It can be used on networks from 6 to 132 kV for the following applications:

LINETROLL 3600 PDAC: installed on strategic points in the network (switching points, branching points),

it assists the operator by visually signaling the passage of a single- or multi-phase fault current.

LINETROLL 3600 PDAT: when used in combination with remote-controlled switchgear, it assists the oper-

ator in remote control by providing contacts that alert the remote control system to the passage of a PTG or

PTP fault current.

LINETROLL 3600 PDAU: installed temporarily on a disturbed network, it identifies what sections are

responsible for faults and gives a time and date system the data required to analyze faults, whether persist-

ent or transient.

Description and working principle

The LINETROLL 3600 works on the principle of directional fault indication described in EDF patent 9209549.

The following block diagram shows the LINETROLL 3600 indicator's main circuits.

In the initial milliseconds after a PTG fault, voltage and current transients are generated on the system. Using

a microprocessor to interpret the phase displacement between residual voltage and residual current, the cir-

cuit can indicate in which direction the PTG fault is located (up-line or down-line of the support the pole is

strapped to).

For PTP faults the working principle is that of an ammeter (current threshold).

Application of a LINETROLL 3600 FCI

General

When a LINETROLL 3600 detects a fault current, it alerts the operator either visually with a signal light or

through contacts (LINETROLL 3600 AT or AU).

As soon as the existence of a fault is confirmed, the signal light on the LINETROLL 3600 lights up and stays

lit until one of the following events occurs:

- Forward voltage returns to the HV line (voltage reset).

- The internal 2 hour time delay ends (timer reset).

- The operator resets the fault indicator using either the "manual" system on the box or the COMTROLL

infrared remote control unit (manual reset). The device can be reset manually by turning the display unit

to the signal light reset position and then turning it back to its original position.

PTG fault indication

The principle of directional PTG fault indication is to locate what part of the line is the origin of a PTG fault.

To do this, the LINETROLL 3600 PTG fault indicator has two signal lights:

- A Red light on the front of the box

- A Green light on the back, on the side where the device is supported.

If the GREEN signal light is lit up, the fault is on

the GREEN side, i.e. the side of the support.

If the RED signal light is lit up, the fault is on the RED

side, i.e. the side opposite the support.

PTP fault indication

In this case the LINETROLL 3600 FCI works like a convention-

al fault indicator and no direction is indicated. All the fault indi-

cators between the feeding substation and the fault flash the

green signal light and the red signal light alternately

(once every second).

Sensitivities are defined in the reference set-up shown below.

Please inquire for any other set-up desired.

PTG faults

Any PTG fault characterized by a residual current over

60A peak + 10A and a residual voltage of 9kV + 2kV

is detected.Once those thresholds are exceeded, the

fault indicator waits 40 ms to detect a residual voltage

Vr greater than 3.5kV + 0.5kV before indicating that

there is indeed a fault.

PTP faults

Any PTP fault characterized by a current over 450Arms

+ 80A is detected.

Double PTG faults

A fault considered as a "double PTG fault" consists of

a simultaneous PTG fault on two different phases in a

system powered by the same HV transformer but

grounded at two geographically distant points. The

two faults may be located on the same feeder or on

two different feeders. In this case any fault character-

ized by a residual current over 250Arms + 50A is

detected.

Return of forward voltage

The return of forward HV voltage (resetting the FCI) is

accepted when voltage on the system is at least

10kVrms + 2kV.

The LINETROLL 3600 FCI consists of four parts:

• A support to be strapped on the pole with a metal strip. That

support may have openings for wiring to connect the device

to other equipment and a connection to a time and date

system.

• A main box containing the sensors, the electronic boards and

the batteries.

• A display unit on the bottom of the box. That display unit may

be rotated 90° to improve visibility if required. It is also used

to reset and test the fault indicator.

• A top cap screwed onto the main box. That cap may be

equipped with an optional solar panel to power the FCI.
